考虑到非晶合金具有独特的无序微观结构,其表现出极为复杂的弛豫动力学特性.动态弛豫行为在非晶合金中普遍存在,深刻理解其机制对于解构非晶合金固有的非均匀微观结构至关重要.少量元素的添加是调控非晶合金微观结构有效手段之一.本研究以玻璃形成能力良好的Cu_(46)Zr_(47-x)Hf_(x)Al_(7)(x=0,8)非晶合金为模型合金,运用动态力学分析方法研究复模量随频率和温度的变化,进而探究Hf元素取代Zr元素对动态弛豫的影响.在动态力学频率谱中,借助准点缺陷理论阐明非晶合金在玻璃转变温度T_(g)以下处于等构型状态,准点缺陷浓度保持恒定;而在T_(g)以上,准点缺陷浓度随温度的上升呈线性增加.Hf元素的添加会降低玻璃体系等构型状态下的准点缺陷浓度,并抑制原子迁移能力.通过获取连续和离散的弛豫时间分布,直观展示了非晶合金的动力学非均匀性特征.在动态力学温度谱中,Hf元素的引入增加了玻璃体系的混合焓,抑制了β弛豫强度.进一步从内耗角度表明,Hf元素的引入不仅提高了与β弛豫相关的基本结构单元的激活难度,还增加了整个β弛豫过程的激活能.

Back.round: Cosmetic formulations, and particularly solar products which contain mineral and chemical UV-filters, are often suspected of causing harmful effects on marine fauna and flora. After the publication of our work.in 2019 concerning the ecotoxicological effects of such formulations on corals (Seriatopora hystrix), we here provide some new information about the biodegradability and the ecotoxicological effects of these products on marine zoo- and phytoplank.on. Therefore, we choose to realize in silico and in vitro studies of the biodegradability of several solar products but also to evaluate the ecotoxicological effects of these products on one phytoplank.on, i.e. Phaeodactylum tricornutum, and one zooplank.on, i.e. Acartia tonsa, of a great importance for sea species survival (notably as sources of food). Materials and methods: Two different approaches were used to study the biodegradability of the tested products: One in silico method and an in vitro one. 2 solar products were involved in the in silico study which consisted in the determination of the degradation factor (DF) of each ingredient of the tested formulas in order to finally obtain their estimated biodegradability percentage. Already available data concerning each ingredient coupled to a computer model developed with one of our partners were used to achieve this study. The in vitro study involved 8 formulas containing UV-filters and was led by following the OECD 301 F guidelines. Ecotoxicological studies of 7 of the formulas containing UV-filters were for their part realized by following the ISO 10253 guidelines for the experiments led with Phaeodactylum tricornutum, and the ISO 14669 guidelines for the experiments led with Acartia tonsa. In these studies, the effect of each tested product on crustaceans’ mortality and algal growth inhibition was assessed. Results: The in silico study predicted that formulas containing chemical UV-filters display a high biodegradability (superior to the threshol

Wherever people live together in or near homelands that harbour joint natural resources such as forest, water, minerals, oil etc., they must collaborate, co-exist and share these resources irrespective of their genetic, social, cultural, and political peculiarities. This is not always the case when self-interest, ethnic divisions, elitist politics, economic interest and power tussle set in. The Nso and Ok. people who reside in the Ngongbaa Forest area constitute an example of joint management of resources where at one period, their relationship over the management of the Ok. Mountain Forest was cordial and at another, the relationship became conflictive. This study was designed to study the influence of the k.FP forest management policies on the Nso indigenous forest Management system in Ngongbaa Forest, and its implications. The data collected for the study was secured through the administration of a questionnaire to residents of 10 villages adjacent to the Ngongbaa Forest, and forest users who carried out livelihood activities there between 1963 and 2015. These forest user groups include beek.epers, rat trappers, grazers, mushroom gatherers, ground honey/tree honey harvesters, carvers, etc. The investigation also extended to the traditional leaders of Nso and Ok. who are in charge of the land tenure systems. The findings show that the Ok. Mountain Forest is jointly owned by the Nso and Ok. people. The Nso own the eastern half of the forest k.own as Ngongbaa Forest while the Ok. own the western half, k.own as the k.lum Forest. The cordial relationship that existed between these people ensured the conservation of the forest. But the conflicts that later set in, especially due to the creation of the k.lum Mountain Forest Project in 1987 later changed to the k.lum Ijim Forest Project (k.FP) in 1992 sidelined the local communities which was contrary to the dispositions of the new Cameroon forest law enacted in 1994. Thus, the indigenous conservation practices became ig
